Specifically, embodiments of the present disclosure relate to an apparatus, system, and method for manufacturing a tiled solar cell.

Solar cells are photovoltaic devices that convert sunlight directly into electricity. The efficiency of a solar cell can be affected by an active area on the front surface of the solar cell that is exposed to light to convert sunlight to electricity. Due to the presence of electrical contacts, such as fingers and / or bus bars, on the front surface of the solar cell, the effective area can be reduced. The presence of electrical contacts on the front surface of the solar cell can thereby reduce the module power of a solar cell module composed of solar cells.

The method for operating the described device includes a method aspect for performing each function of the device.

Reference will now be made in detail to various embodiments of the present disclosure, one or more examples of which are illustrated in the accompanying drawings. In the following description of the drawings, the same reference numerals refer to the same elements. Generally, only the differences from the individual embodiments are described. Each example is provided by way of explanation of the disclosure, and is not intended as a limitation of the disclosure. Furthermore, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield further embodiments. The description is intended to include such modifications and changes.

The solar cell arrangement of the present disclosure may be a tile-type solar cell, and it may also be referred to as a "super cell" or "super cell". Solar cell arrangements can be used in solar cell modules. Solar cell arrangements can be made from a number of partially overlapping solar cells (also known as "solar cell elements"). Adjacent solar cells are electrically connected to each other in the overlapping area. The solar cells are connected in series so that the current generated by the individual solar cells flows along a series of solar cells to be collected (for example, at the end portion of the solar cell arrangement). Overlapping configurations can provide efficient solar cell arrangements. Specifically, the solar cell arrangement allows the module power to be increased by increasing the use area or the effective area. Typically, overlapping configurations can increase module power by, for example, 20 to 40 watts. The use area or the effective area may correspond to an area illuminated by sunlight and participating in power generation. For example, the use area or effective area may correspond to an area where the solar cell is not covered by, for example, a wire pattern such as fingers and / or a bus bar.

In some cases, a solar cell arrangement of a solar cell arrangement may have high resistance and / or low efficiency when compared to other solar cell arrangements of a solar cell arrangement. The overall efficiency of the module power including (but not limited to) a solar cell arrangement and / or a solar cell module can be largely influenced or determined by a solar cell having high resistance and / or low efficiency. This low-quality solar cell specifically serves as a "bottleneck" in the arrangement of solar cells.

Embodiments of the present disclosure separate (eg, cut) solar cells into smaller pieces that are then sorted and assigned to at least two different solar cell arrangements. For example, each solar cell may be assigned to a respective solar cell arrangement based on one or more geometric and / or physical properties of the solar cell. The solar cell arrangement may thus be made from solar cell elements having similar characteristics and / or quality, and the overall efficiency of the solar cell arrangement may be improved. The module power of a solar cell module with a solar cell arrangement can be increased, specifically because the "bottleneck" caused by low-quality solar cells can be avoided.

For example, the separation device 310 is configured to sequentially or simultaneously divide the first solar cell and the second solar cell into two or more first solar cells and two or more second solar cells, respectively. .

In one example, the first solar cell and the second solar cell may be sequentially input into the separation device 310 using, for example, the first input conveying device 302 or the second input conveying device 304. The separation device 310 may sequentially divide the first solar cell and the second solar cell into two or more first solar cells and two or more second solar cells, respectively. Each piece is then assigned to a respective solar cell arrangement, for example, based on one or more properties of the solar cell piece, such as geometric and / or physical properties.

A (middle) piece that is a full square piece can be assigned to another solar cell arrangement, for example a second solar cell arrangement.

Electrical, optical, or combined electrical and optical properties may be selected from the group consisting of electroluminescence, photoluminescence, and electrical properties.
